TL;DR - I had a shrimp become paralysed and die with no obvious red flags and stable water parameters. I found about 10 hydra and would like to know if I can treat with LCA Planaria Fix without harming my shrimp, particularly my berried shrimp and new shrimplets.
First, let me say thanks to everyone for all the info on this site, especially Jayc and sdITBfanUK for your many years of patient advice, you've already helped me more than you know!
I am a new blue cherry shrimp keeper and everything had been going pretty great for me shrimp-wise. I have a 41L/9 imperial Gallon tank which I cycled/matured for about 6 weeks before adding shrimp (the tank cycled in 2 weeks, but I left it a bit longer). I then got 11 blue cherry shrimp 7 weeks ago and as I said, everything had been going pretty well. 5 of my females matured and berried with what looks like a lot of eggs, and the shrimp always seemed happy and normal.
About 1.5 weeks ago I found 1 dead male shrimp which looked almost stuck in the substrate at the back of my tank. It had turned white/pinkish by the time I found it and I have no idea how long it took for me to find. I wrote it off as everything else seemed fine. Then 2 days ago I saw what looked to be Scutariella on a few of my shrimp, including 2 of the pregnant ones. There was 1-3 little white things sticking up from their noses that seemed to move independently. So I salt dipped the affected shrimp, which cleared the obvious white things and the shrimp all seemed normal. Then yesterday I found a shed with some eggs still attached to it. I believe they were from my first female to become berried due to their colour, she had been berried for about 4 weeks. I thought that it may be from the salt dip.
Things got worse that evening when I found one of my shrimp upside down, apparently dead. I went to get it out of the tank and it attempted to swim around before falling back to the substrate. It looked as though its body was paralysed, but its extremities could still move. It otherwise appeared fine, and had nothing obviously wrong with it. I put it in a small container with clean, prime-treated water as I had read of some people having a similar thing happen due to either toxicity or lack of oxygen. I also topped up the tank and threw in a small sponge filter to increase aeration in case (I don't think it was that as all the other shrimp and snails were acting normally). The afflicted shrimp's movements decreased until I thought it was dead, then about 1 hour later it appeared to be increasing its movements and even flexed its tail a few times but then movement decreased again and it actually died.
My tank parameters have been stable the whole time my shrimp have been in there, and I was wracking my brain trying to work out what could possibly have happened. Tonight I found about 10 tiny hydra in my tank and I am wondering if there is a possibility that the dead shrimp could have been stung by a hydra? Especially if she had just moulted? She may have been the one that lost the eggs, but there is another shrimp with similar markings that I have seen wandering around with no saddle, and as all my females have been either berried or saddled the last week or so, I thought that that one was probably the female that shed her eggs. There were some other moults as well though.
My tank parameters are:
Ammonia and Nitrite: 0
Nitrate: 5-10ppm (this is what they are constantly, and I struggle to tell the two apart, if anything the colour was a little lighter)
Temp: 22 celsius
I use a thermometer, TDS and a Ph metre, salifert phosphate test kit and API liquid test kits for everything else.
I have been doing about 20% water changes once a week and slow drip the freshwater in. I use tap water (and this is what the shrimp were raised in) treated with prime. I have plants, driftwood, dragon stone, Indian almond leaf and a small piece of cuttlebone. These things have all been consistent since the beginning (I added the cuttle bone after cycling to slightly increase my Ph and its been very stable since. I use LCA shrimp safe all-in-one fertiliser at about .75 of the recommended low light dose twice per week, Seachem advance, and 1/8tsp LCA potassium sulphate added at water change. I was due to change water today, so I do not think it is that. All the other shrimp seem happy and normal. I did rearrange the tank about 2 weeks ago and got rid of some Vals that were spreading everywhere and looking scraggly and added a couple of new plants. There has been a bladder snail boom over the last week or so and brown dust and a little green spot algae on the glass. I have been having issues with getting the plants to grow nicely, but there is still a decent amount of growth.
I should also mention that I get chemical triggered migraines and so there are no spray chemicals of any kind in the house, and am extremely careful of scented products and any chemical use, so I don't think anything could have gotten into the tank. I have kept frogs (who are very sensitive to chemicals) for 8 years with no mishaps.
In good news, my first shrimplets were born today, I have seen at least two :), so it has been a roller coaster! I have some LCA Planaria fix as I found one hydra (bigger than the current ones) just before adding my shrimp. However, after removing that one I could not find any trace of more despite daily careful checking, so I held off on treating. Would it be ok to use that now? I can't seem to find what the actual ingredients are. I am worried about hurting the shrimplets and the berried shrimp, but obviously hydra are a danger to them as well. Please help :).
I think I put in all the necessary info, sorry for the long post, thanks for sticking with it if you kept reading :).

I recently put in an order for 12 blue dream and 12 cherry shrimp. The shipping was delayed, Harrisburg PA distribution is terrible. Took over 9 days for them to arrive. 0 DOA. Nice! Anyway I've had them now for I'd say 2 weeks. One already is pregnant! And I recently found a guest staying. I have copepods all over, I heard they are fine. I'm not sure what this is. Looks to have antennas, like a snail or something.

My area of Michigan (48065) seems to be a black hole for shrimp enthusiasts, and my hope was to uncover folks I can buy shrimp (and hopefully moss) from locally. Since the pandemic has paused all face-to-face meetings for local clubs until further notice, it's been rough (and I can't imagine paying online retail ridiculous prices for shipped shrimp)!
Since we only have the "City" field (for location) on profiles, is there a better way to find local people? I'd love any help you can offer.
Okay, so the title pretty much says it all... One of my berried tts just moulted, and she left the eggs in the moult. What happened, and why?
I'm going to try to save the eggs with some sort of extraction, and I'll be very careful. She was pretty far along. I think I'll use the net over bubbler method. Does anyone have experience with this, and particularly the extraction? I won't do anything until I have some idea to go off.
Thanks in advance.
Oh and the moult is under like 2 hours old. Wasn't there when I started watching a movie, was there when I checked back after.
Going off this video:
Hoping the process will be similar.
So I got myself a little 5 gallon (20L) recently (it was free!) to use for quarantine. I’m going to use it to qt some cory cats and maybe some tetras or gouramis for my community tank. The thing is, I’ve got it set up really nicely in my room and I want to have it actually stocked. I definitely don’t want a betta, but I found some super cute guppies on gumtree (Wild Thai Orchid) that I can never find locally. How many guppies do u think I could get in the tank?? The seller only has 4 pairs, so is selling in pairs but not trios, so that could have an affect on the amount. I also plan on adding shrimp, either of a neo or caridina variety, or native - like dae or chameleons.
So my questions are: how many guppies could go in the tank (assuming they breed and I keep the babies in with them for about a month each time), could I fit in anything else (with a pair or 4), like a couple of chilli rasboras or rocket killies, and will the shrimps be enough for a cleanup crew, or should I add an Otto or something?
